"WebDec 17, 2011 · In a linear system we saw that work = Fd. In a rotational system torque (t) - which consists of force and radius - replaces force (F), and distance (d) becomes the angle through which the torque acts. This means work = tθ, where θ is the angle. In the case of an electric motor, θ is 360-deg or one complete rotation. " - How motor units work

Web3. Synchronization of motor units. This refers to the ability of the nervous system to synchronise the discharge of action potentials in multiple motor units. Importantly, synchronization of motor units refers to the synchronization of motor units with a similar recruitment threshold: for instance, the synchronization of type 1 motor units. WebOct 24, 2024 · The size principle — Peripheral fatigue changes the recruitment (force) threshold of motor units, although this does not affect the order in which the motor units are recruited. When a muscle is fatigued, the recruitment (force) threshold reduces. So high-threshold motor units are recruited at lower levels of force.
